Soft Alley
Five stops tuned to sit together without fighting — #78155e ink anchors the set, #e893ca opens it up, and #a34686, #c161a2, #ca77ad cross the middle in a monochromatic arrangement. Soft Alley suits event posters that compete with a wall of other posters. The darkest and lightest stops clear AA as a text pair.
